It happens a lot if I'm honest, since the new update! It's just really annoying because sometimes I spend forever on a drawing and then KABAM!! It's ruined! It only seems to happen on certain parts of the screen, though??If any of you have the same problem, know how to fix it, or want to say something irrelevant please reply to this with @Musketeer_1234 (me) in it... Thanks for reading and potentially helping!!!Thanks for helping everyone!!!
